' V SMOKERS PIPE Filed Au 27, 1936 Franli'f'a'ekl,

INVENTOR ATTORNEY Patented Aug. 9, 1938 UNITED STATES PATENT 7 Claims.

My invention relates to improvements in smokers pipes and has for its primary object the provision of novel means for catching and preventing passage to the bit of unpleasant and noxious substances, the nature of the construction being such that it is susceptible of easy and instant cleaning.

More specifically, it is an object of the invention to provide in a pipe stem, a sectional and removable baffle element carrier, the arrangement of baffie elements being such as to hold the carrier assembled when the same is being inserted or removed from the stem.

Other objects and advantages of the invention will be readily apparent to those skilled in the art upon reference to the accompanying drawing in connection with the detailed descriptive matter appearing hereinafter.

It is to be understood that the drawing illustrates a now preferred embodiment of the invention although it will be clear that same is susceptible of considerable change and modification within the spirit and scope of the subject matter claimed hereinafter.

In the drawing, wherein the same reference characters have been used to designate the same parts in all views,

Figure 1 is a longitudinal sectional View through a pipe incorporating my invention;

Figure 2 is a perspective view of one of the baflle element carrying sections;

Figure 3 is a cross-sectional View taken on the line 3-3 of Figure 1;

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1.

Referring to the drawing by reference characters, the numeral 5 designates the bowl of a pipe having the bit section 6 detachably connected thereto by means of the stem sleeve Ii],

Such sleeve III fits onto the short boss I at one side of the bowl and which boss has opening from its outer end the chamber 8 which communicates with the bowl 5 through the downwardly extending passage 9.

Insertible within the stem sleeve I 0 is a split tube or baffle carrier member comprising matching sections I I, I2. 7

Each section of the split sleeve or baffle carrier II, I2, is provided with a plurality of transverse grooves spaced in the direction of the length of the baffle carrier. The grooves of the section II are designated as at Ila while those of the section I2 are designated as at IZa. Corresponding grooves of each section are arranged to match or align with one another so that the baffle plates or members I3, which are received in the grooves I la of the section I I extend into the grooves In of the section I2 as clearly shown in Figure 1. Figure 1 also demonstrates that the baflie members I4 which are carried in the grooves lid-' of the section I2 extend into the grooves IIa of the section II. However, as indicated, the bafile members I3 of the section II terminate short of the opposed wall portions of the carrier section I2; and likewise the bafile members I4 '10 of the carrier section I2 terminate short of the opposed wall of the carrier section I I. Inasmuch as the baille carrier member II, I2 is circular the grooves I211 of the section I2 which are arranged opposite the bafile-carrying grooves IIa of the l5 section II serve to confine the baffle plates or members I3 therein. The same is true as to the grooves IIa of the section II which are arranged opposite baffle carrying grooves of the section I2 and receive the outer ends of bafiles I4 thereof. 20

As best shown in Figure 1 and also indicated in Figure 2, the sections I I, I2 of the split sleeve or bafiie carrying member are preferably stampings. A suitable die is used to impress the grooves IIa, IZa in the sections I I, I2 and also give the 25 same the desired transverse curvature.

Particular attention is directed to the fact that the sections II, I2 each have at their side edges the laterally extending flange which, as to the section II, is designated as at Me and as to the-30 section I2 at I20. These flanges extend outwardly to lie just beyond the plane of the adjacent edges of the ribs IIb, IZb of the respective sections I I, I 2 and engage in longitudinal grooves IIIa in stem III as shown in Figures 3 and 4. By "35 this construction the sectional sleeve or carrier member I I, I2 for the baflies I3, M is held against rotation in stem IE] and has a multiple point contact or engagement with the interior surface of the stem as clearly shown in Figs. 1, 3 and 4.40 Furthermore, the engaging flanges Ha, I 20 of the sections II, I2 of the baffle carrier sleeve serve to reinforce said sections and hold them in shape aside from guiding the assembly to and from operative position in stem Ill. 45

Turning to Figure 1 it will be observed that the inner end of the bit 6 is cored out to provide the chamber I6 forming a continuation of the baffle carrier or sleeve II, I2. This chamber I6 flares outwardly and the bit engages the ends of the 50 sections II, I2.

The bit 6 provides the draft passage 6:1, as shown, which receives the tubular member I5 whose inner end extends into the chamber I6. This prevents the smoker from drawing saliva 55 or moisture into his mouth from the chamber l6.

Still referring to the bit 6, as shown in Figure 1, it will be noted that it is provided with an exterior reduction over which fits the outer end of the stem 10, there being provided a shoulder Ilia against which the outer end of such stem HI abuts.

The stem l0 fits upon the boss 1 and upon the reduction of the bit with a snug friction fit so that the parts will be held assembled while the pipe is being smoked. However, it will be obvious that it is a very simple matter to pull the bit and bowl section apart and force the baflle carrier member out through one end of the stem I 0. While the bafile carrying member ll, I2 is being forced out of the stem l0, it will be apparent that the bafile members l3, [4 will hold the sections H, 12 assembled by reason of the fact that the baflle members [3, M of the sections H, I2 engage in opposite grooves Ha, Ha of said sections. However, as soon as the bafile-carrier member ll, l2 has been forced out of the stem II] the parts ll, [2 can be readily separated and cleaned.

The pipe as shown and described is a very agreeable pipe to smoke for the reason that the products of combustion are caused to follow a tortuous passage through the baflle carrier member ll, I2, the baffles l3, M of which intercept and collect noxious substances.

The formation of the sections ll, 12 by a stamping process, or otherwise for that matter, is very advantageous in that it provides the external ribs lib; l2b on the members ll, [2. These ribs and also the side flanges I I0, I form heat disseminating fins or portions which make for a cool smoke; and the spacement of the stem Ill from the member H, l2 except where portions l lb, [2b, Hc, I20, engage, prevents stem [0 from becoming hot. I preferably provide stem ID with several series of circumferentially spaced holes Hlb to allow circulation of air into the space between the stem and bafile sleeve H, i2.

From what has been said it will be apparent that a highly practical, simple and efficient struc-- ture has been provided.

Having thus described my invention, what I claim as new is:

1. A smoking pipe comprising in combination, bowl and bit portions, said bowl having a short smoke outlet-providing boss, a stem member comprising a longitudinally split sleeve providing two cooperating sections having transverse grooves, spaced in the direction of the length of the stem, corresponding grooves of the respective sections being arranged in matching communication with one another, transversely extending baille partitions carried in alternate grooves of the respective sections and engaging in opposed grooves of the other section and terminating short of the opposed wall of such second-mentioned section whereby to hold such sections against longitudinal shifting, and a sleeve member extending beyond the ends of said stern section and having connection with said bowl and bit.

2. A smoking pipe comprising in combination, bowl and bit portions, said bowl having a short smoke outlet-providing boss, a stem member comprising a longitudinally split sleeve providing two cooperating sections having transverse grooves, spaced in the direction of the length of the stem, corresponding grooves of the respective sections being arranged in matching communication with one another, transversely extending baffle partitions carried in alternate grooves of the respective sections and engaging in opposed grooves of the other section and terminating short of the opposed wall of such second-mentioned section, whereby to hold such sections against longitudinal shifting, a sleeve member extending beyond the ends of said stem section and having connection with said bowl and bit, and the exterior surface of said baflle partition-carrying stem sections having transverse ribs at the site of said grooves and engaging the interior surface of said sleeve wall whereby to provide dead air spaces between adjacent ribs.
